[Q] root att galaxy s 2 tether issue - AT&T Samsung Galaxy S II SGH-I777

stock rom, only delete original tether apk which att put restriction on it.
it won't work with encryption on, open access is fine.
security only have two option: open or WPA2PSK.
any one have some issue, any fix?
is it due to rom problem or root problem?

No problem with WPA2 PSK. You really don't want ot use any other encryption.

my encryption doesn't work well with my ps3 so I use open too

looks like encrypted tether is working for some one.
any idea why some device is not working? due to lack of tether plan?
for root phone, if just copy other tether apk to it, will it work?

---

Mine is rooted and tethering manager removed just like yours.
The problem is probably with your other devices that try to use the wi-fi hotspot. They are not compatible with your phone. Do they all support the WPA2 PSK encrytion? I'm not sure if the phone is using WPA2 AES encryption or WPA2 TKIP encryption.

Use letters and numbers for the password if you don't do it already.
That fixed it for me when it it didn't worked, well was on a Xperia Arc but should work for you, too.

I change my APN to get away from strict NAT. There are a multitude of APN settings for ATT. Some give me great speeds, some have strict NAT, so you will have to try different ones. I've posted 2 screenshots of the 1 I use for fast speed & Moderate NAT.
